Abstract (en)
[origin: US2017226298A1] Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. Also disclosed herein are articles including the water-soluble film and containing a composition such as a household care composition. The PVOH resin blend includes a PVOH copolymer including one or more types of anionic monomer units such as a PVOH terpolymer and a PVOH polymer such as a partially or completely hydrolyzed PVOH homopolymer. When the PVOH copolymer and PVOH polymer are blended in particular proportions and/or selected with regard to various criteria related to the 4% solution viscosity of one or both of the PVOH polymer(s) and PVOH copolymer(s), the resulting water-soluble film formed from the PVOH resin blend exhibits substantially improved aqueous dissolution properties.
